Speech and listening-in IC

It can be calculated from Fig.7 that the AC modulator gain

can be written:

• V---V--O--L--S-N--P- = -(---Z----l-i--n---e-----+---Z--Z--l-i-Sn---Ee---T-----)-----×----2----4- = 12 providing

ZSET = Z line

• Gv (LN to OSP) = 21.6 dB.

The frequency response for audio frequencies of the

sending channel is flat in this case for a complex line

termination.

Set impedance: pins ILS, SIMP and LN

The TEA1096/TEA1096A provides an active set

impedance in both the receiving and sending conditions,

thus allowing a flat frequency response for a complex line

impedance, without the need for any extra compensation

network.

As can be derived from Fig.8 the set impedance ZSET is

10 times lower than ZSIMP.
